Pornhub - which attracts 38 million users a day - said that computers are still the number one platform for accessing its porn, but portable devices are steadily increasing.

"Over the past year, Pornhub has seen a major shift in the types of traffic coming to our site," the website stated. "Of the 38 million people who visit Pornhub each day, over half are now using mobile devices like tablets and smartphones."

On the tablet front, Safari's 73% lead is followed by Chrome with 13% and the Android browser with 7.8%.

Mobile porn viewers are more equal, although iPhone Safari users still take the lead with 38.2%. The Android browser comes in second at 29.4%, while Chrome finishes third at 18%.

Safari users also notched up the second highest page viewers as well, averaging 9.7 pages on mobile and 9.4 pages on tablet - only to be topped by 10.1 pages on mobile with Internet Explorer and 9.8 pages on tablet with Amazon Silk.

On average, Safari users also spend 8.48 minutes on an iPhone and 10.33 minutes on an iPad, beaten again by Internet Explorer (8.57 minutes) and Amazon Silk (12.33 minutes) respectively.
